If you are interested, I use a configuration for zsh that I see as "a shell with features like fish and a syntax like bash"

In .zshrc:

    ZSH="$HOME/.oh-my-zsh"

    if [ ! -d "$ZSH" ]; then
        git clone --depth 1 git://github.com/robbyrussell/oh-my-zsh.git "$ZSH"
    fi

    DEFAULT_USER=jraph

    plugins=(zsh-autosuggestions) # add zsh-syntax-highlighting if not provided by the system

    source "$HOME/.oh-my-zsh/oh-my-zsh.sh"

    PROMPT="%B%{%F{green}%}[%*] %{%F{red}%}%n@%{%F{blue}%}%m%b %{%F{yellow}%}%~ %f%(!.#.$) "
    RPROMPT="[%{%F{yellow}%}%?%f]"

    EDITOR=nano

    if [ -f /usr/share/zsh-syntax-highlighting/zsh-syntax-highlighting.zsh ]; then
        source /usr/share/zsh-syntax-highlighting/zsh-syntax-highlighting.zsh # Debian
    elif [ -f /usr/share/zsh/plugins/zsh-syntax-highlighting/zsh-syntax-highlighting.zsh ]; then
        source /usr/share/zsh/plugins/zsh-syntax-highlighting/zsh-syntax-highlighting.zsh # Arch
    fi

Relevant packages to install: git zsh zsh-syntax-highlighting

Then:

    zsh

WARNING: it downloads and executes Oh My Zsh automatically using git. You may want to review it before.

If it suits you:

    chsh

Works on macOS, Arch, Debian, Ubuntu, Fedora, Termux and probably in most places anyway.

You may need this too:

    export TERM="xterm-256color"
